[adsl] ADSL2 enabled exchanges?

[Tom Parker]

Hopefully this will improve the signal to phishing ratio.

Does anyone know how you would find out if your exchange is ADSL2
enabled? I did some searches and didn't come up with anything useful. 

I've got a very old 3Com duallink modem and it while it works great, I
only get about 2Mb on a good day. I don't really want to upgrade to a
new modem unless my exchange has been upgraded.

Thanks.
